Unable to generate separate graph from pin

Hi there,
When trying to create a separate graph from a pin, the graph remains empty and the console logs the following error:

Firefox 62.0.2: TypeError: jsonData.series is undefined
Google Chrome 69.0.3497.100: Uncaught TypeError: Cannot read property ‘length’ of undefined
Edge from Windows 10 1803: SCRIPT5007: Unable to get property ‘length’ of undefined or null reference

I’ve disabled all plugins and extensions on all browsers, tried with incognito sessions to no avail. Is this a known bug or I’m doing something wrong?
